Description

Technical Field

[0001] The present invention relates to the technical field of riverbank management, and more particularly to a filling-type dam breach rapid sealing truss device and an emergency rescue method. Background Art

[0002] A dam is an artificial barrier built across a flowing waterway to regulate river flow, improving the quality of life for residents along the river basin, preventing damage from flooding, and preventing crop losses during droughts. Dams can also be used to control floods while storing water, which can then be used directly or indirectly to generate electricity. Because dams often withstand immense water pressure, a collapse could be devastating for residents downstream. Therefore, dams require regular maintenance. However, regular maintenance cannot guarantee that dams will not be damaged by floods, so unexpected breaches require prompt repairs.

[0003] There are many ways to plug a breach. The most traditional method is to use an earth-rock dam to plug the breach. This involves throwing earth and rock directly into the breach, relying on the rock and rock to stabilize in the rapids to form a natural embankment. This method is relatively inefficient, and the earth and rock may be washed away, due to numerous uncontrollable factors. To reduce the amount of earth and rock washed away, steel or bamboo cages can be used to plug the breach, but this is still inefficient and may cause some water seepage. With the development of plugging technology, more emergency rescue methods have evolved, such as steel-wood earth-rock composite dam plugging, spiral anchor rapid plugging, and rubber dam plugging.

[0004] The steel-wood earth-rock composite dam sealing method is to connect the steel pipes driven into the foundation vertically and horizontally, reinforce them with wooden piles to form a steel-wood frame that can withstand a certain pressure and impact force, and fill it with bagged gravel, and then cover it with geotextiles, plastic sheets and other materials. It is a water-retaining dam with comprehensive resistance and anti-seepage capabilities.

[0005] The spiral anchor rapid plugging method uses mechanical anchoring instead of piling, and adopts spiral anchors instead of general piles. The mesh frame is driven by the anchored spiral anchors, and then the filling is thrown to plug the hole. It requires the use of a special anchor machine and a unique construction process, and has high technical requirements.

[0006] The rubber dam plugging method fully utilizes the advantages of rubber dams such as fast inflation speed and easy movement. A rubber dam cofferdam is set up upstream of the breach mouth to create favorable conditions for plugging the mouth and achieve rapid plugging of the breach during flood season. Due to the floating nature of rubber dams, they are not suitable for breach mouths with a certain depth.

[0007] However, these plugging methods in the existing technology still have some shortcomings. For example, the steel-wood-earth-rock composite dam plugging method takes a long time to prepare the composite dam before plugging. If the composite dam is made in advance, it will be difficult to transport, and the formation of the breach mouth is unexpected, so the cycle will be relatively long. It is also inconvenient to place the composite dam at the breach mouth because it is too heavy and requires the help of large equipment. Once it is lowered, it is not convenient to adjust it. When it is lowered, the waves are large and the surrounding construction is somewhat dangerous. The spiral anchor rapid plugging method requires the help of a professional anchor machine, and the process is complicated. Water seepage is prone to occur at the anchor cable, and it needs to be grouted with a mixture of cement and water glass in time. The professional requirements are high, and the temporary breach mouth may not be plugged in time. There is a certain risk when implementing it. The rubber dam plugging method is inflated with air or water inside and is generally used in a row. Anchoring is inconvenient. In addition, it is characterized by a smooth surface and cannot be stacked. It is not applicable to deep breach mouths.

[0008] Therefore, when a breach occurs and there is a lack of transportation conditions and professional construction equipment, quick, efficient and effective leak plugging is an urgent problem that needs to be solved. Summary of the Invention

[0009] In order to solve the above problems, the present invention provides a filling-type dam breach rapid sealing truss device and an emergency rescue method, which has low construction difficulty and easy operation. It is suitable for operations when there is a lack of transportation conditions and professional construction equipment. It can quickly, efficiently and effectively stop leaks and has high operational safety.

[0010] According to one aspect of the present invention, a filling-type dam breach rapid sealing truss device is provided, wherein the dam breach forms a breach opening, and the two sides of the breach opening are called upstream dams and downstream dams. The filling-type dam breach rapid sealing truss device comprises a truss that can be spliced ​​and assembled, a first vacuum-shaped prefabricated pipe bag is arranged in the truss, and a second prefabricated pipe bag is provided outside the truss. The upstream dam and the downstream dam are respectively planted with upstream piles and downstream piles on the water flow side, and the two ends of the truss are respectively connected to the upstream piles and the downstream piles. The truss is located on the water flow side of the breach opening, and the upstream piles and the downstream piles can withstand the impact force of the water flow on the truss. The first prefabricated pipe bag and the second prefabricated pipe bag are used to fill fillers to make the truss settle and block the breach opening. The second prefabricated pipe bag on the outside of the truss can fit tightly against the dam after filling.

[0011] In some embodiments, a blocking plate is provided in the truss. The blocking plate is located on the side of the first prefabricated tube bag close to the water flow to block the water flow on the side of the first prefabricated tube bag. As the filler filled in the first prefabricated tube bag expands, the blocking plate gradually approaches the edge of the truss.

[0012] In some embodiments, the first prefabricated tube bag and the second prefabricated tube bag are both geotextile tube bags and / or rubber tube bags.

[0013] In some embodiments, the fillers used to fill the first prefabricated tube bag and the second prefabricated tube bag are one or more of mud, water, cement slurry, and mortar.

[0014] In some embodiments, the fill-type dam breach rapid sealing truss device further includes a buoy that can be inflated or deflated. The buoy is placed on the water surface, and the truss is placed on the inflated buoy to push the truss to rotate or translate so that the truss is parallel to the breach.

[0015] In some embodiments, the truss is connected to the upstream pile body and the downstream pile body through hoops.

[0016] In some embodiments, the fill-type dam breach rapid sealing truss device also includes a filling mechanism, which is installed on the dam. The filling mechanism includes a mixer and a pump. The mixer is connected to the inlet of the pump, and the outlet of the pump is connected to the first prefabricated pipe bag and the second prefabricated pipe bag through a pipeline.

[0017] In some embodiments, the fill-type dam breach rapid sealing truss device further includes a filling mechanism, which is a cutter suction boat, and the cutter suction boat is used to suck underwater mud and transport it to the first prefabricated pipe bag and the second prefabricated pipe bag through a pipeline.

[0018] According to another aspect of the present invention, an emergency rescue method is provided, which is performed using the above-mentioned filling-type dam breach rapid sealing truss device, and the emergency rescue method includes the following steps:

[0019] Step 1: Determine the depth and width of the breach opening, assemble trusses of the required size, and hang a first prefabricated tube bag that has been evacuated in a vacuum state inside each truss. A blocking plate is placed inside the truss, located on one side of the first prefabricated tube bag. A second prefabricated tube bag that has been evacuated in a vacuum state is hung on the outside of the truss.

[0020] Step 2: Plant upstream piles at the foot of the slope on the water flow side of the upstream dam, and plant downstream piles at the foot of the slope on the water flow side of the downstream dam. The upstream piles are above the water surface, and the downstream piles are above or below the water surface.

[0021] Step 3: Place an inflated buoy on the water surface, and hoist the truss assembled in the first step onto the buoy on the water surface, with one end of the truss rotatably connected to the upstream pile;

[0022] Step 4: Using the buoyancy of the float, the truss is pushed to rotate downstream along the water flow direction. The other end of the truss is rotated to the downstream dam, so that the truss is parallel to the breach. The length of the truss is greater than the length of the breach. The blocking plate is vertical and the side wall of the blocking plate is located on the water flow side. The blocking plate can block the water flow on the side of the first prefabricated tube bag.

[0023] When the downstream pile is above the water surface, one end of the truss is rotatably connected to the upstream pile on the outside. After the truss is rotated into place, the other end of the truss is connected to the downstream pile on the outside.

[0024] When the downstream pile is below the water surface, one end of the truss is sleeved on the upstream pile and can be rotatably connected. After the truss is rotated into place, the other end of the truss can be located directly above the downstream pile. After the truss settles, the truss is sleeved on the downstream pile.

[0025] Step 5: Using local materials, fill the vacuum-sealed first and second prefabricated tube bags with filler. Simultaneously, deflate the buoys and remove them. As the first prefabricated tube bag expands, the baffle is pushed to the edge of the truss by the expanded first prefabricated tube bag. The truss automatically sinks to the foot of the embankment under its own weight. After the second prefabricated tube bag expands, it adheres tightly to the bottom and sidewalls of the embankment.

[0026] Step 6: Repeat steps 3, 4, and 5 to stack and raise the trusses until the height of the stacked trusses is higher than the height of the breach opening, thus completing the sealing of the breach opening.

[0027] According to another aspect of the present invention, an emergency rescue method is provided, which is performed using the above-mentioned filling-type dam breach rapid sealing truss device, and the emergency rescue method includes the following steps:

[0028] Step 1: Determine the depth and width of the breach opening, assemble trusses of the required size, and hang a first prefabricated tube bag that has been evacuated in a vacuum state inside each truss. A blocking plate is placed inside the truss, located on one side of the first prefabricated tube bag. A second prefabricated tube bag that has been evacuated in a vacuum state is hung on the outside of the truss.

[0029] Step 2: Plant upstream piles at the foot of the slope on the water flow side of the upstream dam, and plant downstream piles at the foot of the slope on the water flow side of the downstream dam. Both upstream and downstream piles should be above or below the water surface.

[0030] Step 3: Hoist the truss assembled in the first step to the breach opening, or place an inflated buoy on the water surface, hoist the truss assembled in the first step onto the buoy, and translate the truss on the water surface so that the truss is parallel to the breach opening. The two ends of the truss are respectively connected to the upstream pile and the downstream pile. The length of the truss is greater than the length of the breach opening. The barrier plate is vertical and the side wall of the barrier plate is located on the water flow side.

[0031] When the upstream pile and the downstream pile are both above the water surface, the truss is placed on the buoy on the water surface and translated, and the outer sides of the two ends of the truss are connected to the upstream pile and the downstream pile respectively;

[0032] When the upstream and downstream piles are both at the bottom of the water, the truss is placed on the buoy on the water surface and translated until the two ends of the truss are directly above the upstream and downstream piles. After the truss settles, the truss is sleeved over the upstream and downstream piles.

[0033] Step 4: Using local materials, fill the vacuum-state first and second prefabricated tube bags with fillers. As the first prefabricated tube bag expands, the baffle is pushed to the edge of the truss by the expanded first prefabricated tube bag. The truss automatically sinks to the foot of the embankment under its own weight. After the second prefabricated tube bag expands, it adheres tightly to the bottom and side walls of the embankment.

[0034] Step 5: Repeat steps 3 and 4, stacking and raising the trusses until the breach is sealed.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows: the structure of the filling-type dam breach rapid sealing truss device provided by the present invention is simple, the emergency rescue method has low construction difficulty, convenient operation, and high operational safety, and it can quickly, efficiently and effectively stop leaks, and is suitable for operations when there are no transportation conditions and professional construction equipment. The trusses of standard sizes can be pre-assembled, and the vacuum first prefabricated pipe bags and blocking plates in the trusses can be pre-installed without affecting transportation. When the breach is found, the trusses can be directly transported to the site, and the trusses can be quickly assembled according to the length of the breach so that the trusses meet the length requirements. Then, the second prefabricated pipe bag is hung outside the truss, and the unfilled truss is placed in the water. The truss can be rotated and translated into place along the water using a buoy, or can be lifted and translated into place in the water, which improves safety. Subsequently, the first prefabricated pipe bag and the second prefabricated pipe bag are arranged on the truss. The bags are filled. Since the first prefabricated tube bag and the second prefabricated tube bag are vacuum, they can be filled quickly when the filler is filled, and the blocking plate can block the water flow when the first prefabricated tube bag is filled, which is more conducive to speeding up the filling of the filler. The first prefabricated tube bag and the second prefabricated tube bag can be filled on land or on water. The filler can be made from local materials, such as mud, water, cement slurry, and mortar. The truss automatically settles due to its own weight. The truss has a regular shape and can be stacked in height. Each truss is filled with the expanded first prefabricated tube bag. After the second prefabricated tube bag is expanded, it is tightly attached to the bottom and side wall of the dam. The first prefabricated tube bag of the bottom truss is also tightly attached to the bottom of the dam, which greatly reduces the possibility of water seepage. The two ends of the truss are positioned by the upstream pile and the downstream pile respectively, which can effectively reduce the impact of the water flow on the truss.

[0047] The present invention will be further described below in conjunction with specific embodiments.

[0048] like Figure 3 and 4 As shown, when a river dam breaks, a breach opening is formed. The two sides of the breach opening are called the upstream dam 11 and the downstream dam 12. The breach opening needs to be plugged.

[0049] Example 1

[0050] like Figure 1 、 2As shown in , 6 to 8, a filling-type dam breach rapid sealing truss device according to one embodiment of the present invention includes a truss 2 that can be spliced ​​and assembled, a first vacuum-shaped prefabricated pipe bag 21 is arranged in the truss 2, and a second prefabricated pipe bag 23 is suspended outside the truss 2. The first prefabricated pipe bag 21 and the second prefabricated pipe bag 23 are rolled up when vacuumed, the upstream dam 11 is planted with upstream piles 3 on the water flow side, and the downstream dam 12 is planted with downstream piles 4 on the water flow side, the two ends of the truss 2 are respectively connected to the upstream pile 3 and the downstream pile 4, the truss 2 is located on the water flow side of the breach, the second prefabricated pipe bag 23 is located on the side close to the dam, the first prefabricated pipe bag 21 and the second prefabricated pipe bag 23 are used to fill filler 5 to make the truss 2 sink to block the breach, and the second prefabricated pipe bag 23 can fit tightly against the dam after being filled and expanded.

[0051] Truss 2 is assembled into a cube from 150cm steel frames, supported by diagonal braces, and then assembled into standard truss units with a length of 600cm. Depending on the length of the breach, multiple truss units can be joined to form a truss 2 of the desired length. Pre-installed latches or anchoring joints (not shown) are provided on truss 2 to facilitate the connection of truss units.

[0052] To ensure effective plugging, the length of the truss 2 needs to be greater than the length of the breach opening, and the height of the truss 2 needs to be higher than the height of the breach opening. Therefore, multiple layers of trusses 2 can be stacked according to actual needs.

[0053] A blocking plate 22 is arranged within the truss 2. The blocking plate 22 is located on the side of the first prefabricated tube bag 21 that faces the water flow, thereby blocking the water flow to the side of the first prefabricated tube bag 21. As the filler 5 in the first prefabricated tube bag 21 expands, the blocking plate 22 gradually approaches the edge of the truss 2. To install the first prefabricated tube bag 21 and the blocking plate 22 within the truss 2, the first prefabricated tube bag 21 can be hung on one side of the truss 2. The blocking plate 22 can then be pressed horizontally onto the first prefabricated tube bag 21. When the truss 2 is needed, the truss 2 can be flipped over to position the blocking plate 22 in a vertical position.

[0054] Both the first prefabricated tube bag 21 and the second prefabricated tube bag 23 can be geotextile tube bags or rubber tube bags. The filler 5 used to fill the first and second prefabricated tube bags 21, 23 can be one or more of mud, water, cement slurry, and mortar. The fillable dam breach rapid sealing truss device also includes a filling mechanism for filling the first prefabricated tube bag 21 with the filler 5.

[0055] like Figure 9 and 10As shown, the filling mechanism can include a mixer 71 and a pump 72. The mixer 71 is connected to the inlet of the pump 72, and the outlet of the pump 72 is connected to the first prefabricated tube bag 21 and the second prefabricated tube bag 23 via a pipeline. The filling mechanism can be used to fill mud, cement slurry, or mortar. This filling mechanism is installed on the embankment, which is called onshore filling.

[0056] like Figure 11 As shown, the filling mechanism can also be a cutter suction vessel 73. The cutter suction vessel 73 can suck underwater mud or water as the filler 5 and deliver it to the first prefabricated pipe bag 21 and the second prefabricated pipe bag 23 through a pipeline. This filling method is called overwater filling. In actual application, the filling mechanism can also be a water pump (not shown). When using a water pump, the filler 5 is water. The filler can be obtained locally, which is very convenient.

[0057] The fill-type dam breach rapid sealing truss device also includes a buoy 6, which can be inflated or deflated. The buoy 6 is placed on the water surface, and the truss 2 is placed on the inflated buoy 6. After one side of the truss 2 is rotatably connected to the upstream pile 3, the buoy 6 is used to push the truss 2 to rotate downstream, or the truss 2 on the buoy 6 is translated into position so that the truss 2 is parallel to the breach. When filling the filler 5 into the first prefabricated pipe bag 21, the buoy 6 can be removed by deflating, causing the truss 2 to automatically sink to the foot of the embankment. At the same time as the first prefabricated pipe bag 21 is filled, or after the first prefabricated pipe bag 21 is filled, the second prefabricated pipe bag 23 is filled. After the second prefabricated pipe bag 23 is filled and expanded, the second prefabricated pipe bag 23 can be tightly attached to the bottom and side walls of the embankment. The first prefabricated pipe bag 21 of the bottom truss 2 is also tightly attached to the bottom of the embankment. When placing truss 2, if the construction environment allows for the use of large machinery, the truss 2 can be directly hoisted to the breach opening using a lifting mechanism and placed over upstream piles 3 and downstream piles 4, eliminating the need for buoys 6. However, due to the weight of truss 2 and the inaccessibility of large machinery in harsh construction environments, manual maneuvering of truss 2 into position is impractical. Therefore, the use of buoys 6 allows for the movement of truss 2, improving operational convenience.

[0058] The connection method between the truss 2 and the upstream pile body 3 and the downstream pile body 4 can be diversified. For example, the outer side of the main frame at both ends of the truss 2 can be abutted and fixed with the upstream pile body 3 and the downstream pile body 4, or the two ends of the truss 2 can be covered with the upstream pile body 3 and the downstream pile body 4 by using the collar 25. The preferred method is to connect the truss 2 and the upstream pile body 3 and the downstream pile body 4 through the clamp 24 ( Figure 2 This improves stability and facilitates operation.

[0059] Example 2

[0060] According to another aspect of the present invention, an emergency rescue method is provided, which uses the filling-type dam breach rapid sealing truss device provided in Example 1 to plug leaks. The emergency rescue method includes the following steps: Figures 5 to 7 As shown:

[0061] Step 1: Survey and determine the depth and width of the breach, and set the truss 2 of the required size for assembly, that is, the total length and total height of the truss 2; the truss 2 can be a prefabricated truss unit, for example, each truss unit is 600㎝*150㎝*150㎝ (length*width*height), and a first prefabricated pipe bag 21 that is evacuated to a vacuum state is hung and installed in each truss 2, and a blocking plate 22 is placed in the truss 2, and the blocking plate 22 is located on one side of the first prefabricated pipe bag 21; according to the total length and total height requirements of the truss 2, the truss units are spliced ​​to meet the length requirements, and then the truss 2 that meets the height requirements is prepared; on the outside of the truss 2, on the side close to the dam, a second prefabricated pipe bag 23 that is evacuated to a vacuum state is hung and installed. In this way, the assembly of the entire truss is completed. Figure 2 As shown, one end of the truss 2 has a hoop 24 connected to the upstream pile body 3, and the other end of the truss 2 has a hoop 24 or a collar 25 connected to the downstream pile body 4. The collar 25 is a hollow annular structure.

[0062] Step 2: Quickly plant piles at the toe of the upstream embankment 11, on the water-side slope. Plant upstream pile 3. Plant downstream pile 4 at the toe of the downstream embankment 12, on the water-side slope. Hollow pipe piles are used for upstream and downstream piles 3 and 4, each with a diameter of 600 mm. Pile driving can be accomplished using an excavator connected to a vibratory hammer to form a pile driver. In this embodiment, after the piles are planted, the top of upstream pile 3 is above the water surface, while the top of downstream pile 4 is below the water surface.

[0063] Step 3: Place the inflated buoy 6 on the water surface, hang the truss 2 assembled in the first step onto the buoy 6 on the water surface, place one end of the truss 2 against the upstream pile 3, and install the clamp 24 with bolts to connect the truss 2 to the upstream pile 3. At this time, the connection cannot be too tight. It is necessary to ensure that the truss 2 can rotate around the upstream pile 3 to facilitate the placement of the truss 2.

[0064] Step 4: Utilize the buoyancy of the float 6 and the thrust of the water flow to push the truss 2 to rotate from upstream to downstream along the direction of the water flow, so that the other end of the truss 2 rotates to the downstream dam 12 and is located directly above the downstream pile 4, so that the truss 2 is parallel to the breach opening. The length of the truss 2 is greater than the length of the breach opening. The blocking plate 22 is now vertical and the side wall of the blocking plate 22 is located on the side close to the water flow. The blocking plate 22 can block the water flow on the side of the first prefabricated pipe bag 21.

[0065] Step 5: Using local materials, fill the vacuumed first prefabricated pipe bag 21 with filler 5 through a filling mechanism. The filler 5 can be made of one or more of mud, water, cement slurry, and mortar. At the same time, deflate the buoy 6 and remove it. As the first prefabricated pipe bag 21 expands, the baffle 22 is pushed to the edge of the truss 2 by the expanded first prefabricated pipe bag 21. The truss 2 automatically sinks to the foot of the embankment under its own weight. As the truss 2 settles, the collar 25 at the other end of the truss 2 is placed outside the downstream pile 4, or the truss 2 is connected to the downstream pile 4 using a clamp 24. Simultaneously with or after the first prefabricated pipe bag 21 is filled, the second prefabricated pipe bag 23 is filled using the filling mechanism. After the second prefabricated pipe bag 23 is filled and expanded, it can adhere tightly to the bottom and sidewalls of the embankment.

[0066] Step 6: Because the breach opening has a certain height, repeat steps 3, 4 and 5 to stack and raise the trusses 2 until the height of the stacked trusses 2 is higher than the height of the breach opening. The first prefabricated tube bag 21 of the bottom truss 2 is also in close contact with the bottom of the dam, forming an effective plugging method to complete the sealing of the breach opening.

[0067] The stakes in step 2 are usually planted at 1 / 3 of the length from the top of the slope, and are suitable for water depths of 3 to 8 meters.

[0068] Example 3

[0069] According to another aspect of the present invention, an emergency rescue method is provided, utilizing the truss device for rapidly sealing a dam breach provided in Example 1. Example 3 differs from Example 2 primarily in the manner in which truss 2 is secured to upstream pile 3 and downstream pile 4. In this embodiment, the top of downstream pile 4 is elevated above the water surface. Hoops 24 are mounted at each end of truss 2, which are later secured to upstream pile 3 and downstream pile 4.

[0070] When using this emergency rescue method to plug leaks, when performing the second step of implanting the upstream pile body 3 and the downstream pile body 4, the top of the downstream pile body 4 is above the water surface. When performing step three of placing the truss 2 on the pontoon, one end of the truss 2 is placed against the upstream pile body 3, and the clamp 24 is installed by bolts so that the truss 2 is connected to the upstream pile body 3. It is necessary to ensure that the truss 2 and the upstream pile body 3 are rotatably connected. After the truss 2 is rotated into place downstream using the pontoon 6, the other end of the truss 2 is rotated to the downstream pile body 4, and the clamp 24 is installed by bolts so that the truss 2 and the downstream pile body 4 are fixed, but not fixed. It is necessary to allow the truss 2 to settle automatically. Then fill it again, and use its own weight to make the truss 2 automatically settle to the foot of the embankment slope.

[0071] Example 4

[0072] According to another aspect of the present invention, an emergency rescue method is provided, which is performed using the filling-type dam breach rapid sealing truss device provided in Example 1. The main difference between Example 4 and Example 2 is that the truss 2 is placed in a different way. The emergency rescue method includes the following steps: Figure 8 As shown:

[0073] Step 1: Survey and determine the depth and width of the breach opening, setting the required dimensions for truss 2 assembly, namely, the total length and height of truss 2. Truss 2 can be prefabricated truss units, with a first, prefabricated tube bag 21, evacuated, suspended inside each truss 2. A baffle 22 is placed inside the truss 2, located on one side of the first prefabricated tube bag 21. Based on the required total length and height of the truss 2, the truss units are spliced ​​to meet the required length, and then a truss 2 is prepared to meet the required height. A second, prefabricated tube bag 23, evacuated, is suspended outside the truss 2, on the side closest to the dam. This completes the assembly of the entire truss. Hoops 24 or collars 25 are installed at each end of the truss 2, which will later be secured to the upstream pile 3 and downstream pile 4.

[0074] Step 2: Plant upstream piles 3 at the foot of the upstream dam 11 on the water flow side, and plant downstream piles 4 at the foot of the downstream dam 12 on the water flow side. The requirements for planting piles are the same as those in Example 2.

[0075] After the piles are planted, if the tops of the upstream pile body 3 and the downstream pile body 4 can be lower than the water surface, this will not affect the buoy 6 carrying the truss 2 to the top of the upstream pile body 3 and the downstream pile body 4. After the truss 2 is settled in the later stage, the truss 2 is sleeved on the upstream pile body 3 and the downstream pile body 4. At this time, the two ends of the truss 2 can be set as rings 25.

[0076] After the piles are planted, if the tops of the upstream pile body 3 and the downstream pile body 4 are both above the water surface, the buoy 6 will carry the truss 2 to the front side of the upstream pile body 3 and the downstream pile body 4 in the later stage to fix the truss 2 and the downstream pile body 4, but not to fix them rigidly. It is necessary to allow the truss 2 to sink automatically, and the clamp 24 can be used to fix them.

[0077] Step 3: Place the inflated buoy 6 on the water surface, and hoist the truss 2 assembled in the first step onto the buoy 6. Use the buoy 6 to move horizontally on the water surface to make the truss 2 parallel to the breach. The two ends of the truss 2 are sleeved on the upstream pile 3 and the downstream dam 12 through the rings 25, or the two ends of the truss 2 are connected to the upstream pile 3 and the downstream pile 4 through the clamps 24. The length of the truss 2 needs to be greater than the length of the breach. The blocking plate 22 is vertical and the side wall of the blocking plate 22 is located on the side close to the water flow.

[0078] Step 4: Using local materials, a filling mechanism is used to fill the vacuumed first prefabricated pipe bag 21 with filler 5. The filler 5 can be made of one or more of mud, water, cement slurry, and mortar. As the first prefabricated pipe bag 21 expands, the baffle 22 is pushed to the edge of the truss 2 by the expanded first prefabricated pipe bag 21, and the truss 2 automatically settles to the foot of the embankment under its own weight. Simultaneously with or after the first prefabricated pipe bag 21 is filled, the second prefabricated pipe bag 23 is filled using the filling mechanism. After the second prefabricated pipe bag 23 is filled and expanded, it will adhere tightly to the bottom and sidewalls of the embankment.

[0079] Step 5: Repeat steps 3 and 4, stacking and raising truss 2 until the breach is completely sealed.

[0080] Example 5

[0081] According to another aspect of the present invention, an emergency rescue method is provided, which is carried out using the filling-type dam breach rapid sealing truss device provided in Example 1. The main difference between Example 5 and Example 4 is the different placement method of the truss 2. Example 5 directly hoists the truss 2 under the premise of meeting the requirements of large-scale machinery entering the construction site.

[0082] When using this emergency rescue method to plug leaks, during the second step of implanting the upstream pile body 3 and the downstream pile body 4, in order to facilitate the fixation of the truss 2 to the upstream pile body 3 and the downstream pile body 4, the tops of the upstream pile body 3 and the downstream pile body 4 are generally higher than the horizontal plane. After the truss 2 is fixed to the upstream pile body 3 and the downstream pile body 4, it is necessary to ensure that the truss 2 can automatically sink along the upstream pile body 3 and the downstream pile body 4.

[0083] The filling-type dam breach rapid sealing truss device provided by the present invention has a simple structure, is a low-difficulty emergency rescue method, is easy to operate, and has high operational safety. It can quickly, efficiently, and effectively seal leaks, making it suitable for operations where transportation conditions and specialized construction equipment are lacking. Standard-sized truss units can be preassembled, and the vacuum first prefabricated tube bag 21 and blocking plate 22 within the truss 2 can be preinstalled without affecting transportation. When a breach is discovered, the truss 2 can be transported directly to the site. The truss 2 can be quickly assembled according to the length of the breach, ensuring that the length meets the required length. This allows for flexible use and high assembly efficiency. After the truss 2 is assembled, the vacuum second prefabricated tube bag 23 is suspended on the outer side of the truss 2, on the side closest to the dam. The unfilled truss 2 is placed in water. The truss 2 can be rotated and translated into place in the water by using the float 6 or lifted and translated into place, which improves safety. Then the first prefabricated tube bag 21 is filled. Since the first prefabricated tube bag 21 is vacuum, it can be quickly filled when the filler 5 is filled. The blocking plate 22 can block the water flow when the first prefabricated tube bag 21 is filled, which is more conducive to speeding up the filling of the filler 5. At the same time as the first prefabricated tube bag 21 is filled or after the first prefabricated tube bag 21 is filled, the second prefabricated tube bag 23 is filled. The filler 5 can be made from locally available materials, such as mud, water, cement slurry, or mortar. The trusses 2 have a regular shape and can be stacked in height. Each truss 2 is filled with the expanded first prefabricated pipe bag 21. After the second prefabricated pipe bag 23 is filled and expanded, the second prefabricated pipe bag 23 adheres tightly to the bottom and side walls of the embankment. The first prefabricated pipe bag 21 of the bottommost truss 2 also adheres tightly to the bottom of the embankment, greatly reducing the possibility of water seepage. The upstream and downstream piles 3 and 4 respectively position the ends of the trusses 2, effectively reducing the impact of water flow on the trusses 2. This sealed truss 2 structure can be recycled and reused after the breach is repaired, significantly saving resources.

[0084] The above are only some embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, other variations and improvements can be made without departing from the creative concept of the present invention, and these all fall within the scope of protection of the present invention.
